The CensusCD Neighborhood Change Database (NCDB) presents four decades (1970, 1980, 1990 and 2000)
of tract series data. The data can be presented with either year-specific
boundaries or weighted and normalized to year 2000 boundaries. Data
normalization allows easy time series analysis with identical geographic
boundaries over time. For example, 1980 data can be produced in chart or
map form with the true 1980 definitions, or redrawn using the 2000
boundary designations.

CensusCD NCDB has a subset of the Long Form data for 1970, 1980 and
1990 (and 2000 Short Form data). To see the variables which are
available for each decade go to the following page
http://www.uscensus.net/CensusCD40Years/censuscd40.htm#variables
GeoLytics also offers the full census for these periods (CensusCD 1970;
CensusCD 1980; and CensusCD 1990+ Maps) which offer the complete
Long Form data sets for 1970, 1980 and 1990 with the additional data;
1980 and 1990 also have additional geographic selections. But only the
NCDB product has the data normalized to 2000 boundaries. Information
about these data sets, variable lists, geographies and pricing is available at
http://www.uscensus.net.

The price for CensusCD NCDB is $1,595 for the nation and $845 for a
single state. This will include the Short Form version and a free upgrade
to the Long Form version when it becomes available (about 6-8 weeks).

For each of these data sets, the data has been compressed so that it fits on
1 disk and it comes with built-in mapping capabilities. With a few quick
keystrokes you can generate full-blown maps or tables. You can export the
file data into other systems such as statistical (e.g. SAS, SPSS), database (e.g.
Access, Oracle), spreadsheet (e.g. Excel, 1-2-3), and mapping (e.g. Arc View,
MapInfo) packages.

Note: Tracts do not cover 100% of the geographic areas in 1970, or even in 1980,
as they do in 1990 and 2000. Tracts in 1970 are found mainly in urban areas.
There is complete coverage at the county or MCD level in 1970 and 1980 but this
is only available on the full census products not the NCDB.

We began by creating a survey as a cooperative effort between several high level geospatial leaders, POB staff, and Clear Seas Research market research experts. The survey was sent out to more than 25,000 geospatial professionals who subscribe to POB and/or are members of MAPPS.
